The fruit are formed in an obliquely obovate shape, 2.2 to 3.5 cm (0.9 to 1.4 in) long and 1.6 to 2.3 cm (0.6 to 0.9 in) wide. The fruit are black-pusticulate with a toothed crest found on either side of suture. [3] [4]
Hakea rhombales was first formally described by the botanist Ferdinand von Mueller in 1876 in Fragmenta Phytographiae Australiae . [5] [6] The name of the species is from the Latin word rhombus referring to the shape of the wing on the seed. [4]
